FLANGE-LUBBICATING DEVICE.

Application filed February 24, 1917.

To all whom it may concern:

Belt known that 1, WILLIAM G. J oHNsoN, a citizen of the United States,. residing at McKeesport. in the county of Allegheny and State-of Pennsylvania, have invented certain new and useful Improvements in Flange-Lubricating Devices of which the following is a specification.

This invention relates to new and useful improvements in flange lubricating devices.

This device belongs to the type of lubricators designed for dispensing a suitable lubricant upon the contact or working flange of a wheel adapted for operation upon a track whereby the passage of the wheel over a curved track is greatly facilitated, the present device being especially eflicient upon engines working upon short curves.

The device also provides facilities for varied and accurate adjustment of a lubricant dispenser operatively arranged for use upon a flange wheel, the same including a serviceable pivot connection maintaining a lateral pressure of the device upon the wheel, adjustable limiting meansbeing arranged for controlling the same.

The device is further designed to provide an enlarged area of dispensed lubricant bearing upon a wheel flange and governed by the height of the flange and the condition of the track, the device being of compact arrangement with a large holding capacity for the lubricant to be dispensed thereby.

It is also the object of the device to provide a feeding mount for the lubricator whereby the contact dispensing portion of the latter is resiliently maintained in operative contact with a wheel flange until the same is entirely worn away during the operation of the device. The present construction provides a lubricant dispensing tube constantly held against the flange of the wheel by resilient means allowing the same to follow all of the movements of the wheel while the lubricant is prevented from spreading over the tread of the wheel. In the drawings forming a part of this applica-- tion in which like designating characters refer to corresponding parts throughout the several views- Figure 1 is a View partly in elevation,

Referring more in detail to the drawings it is first noted that the device broadly consists of a lubricant dispenser 10 and a positioning bracket or support 11, the form of the device illustrated in Fig. 1 providing a dispenser in all essentials the same as that set forth in my Patent No. 1, 186,001, dated June 6, 1916, the difference existing being the arrangement of a single piece container 12 instead of the two piece construction of my said patent, a different form and ar 7 rangement of contact tube 13 being provided as well as the mounting means for the device consisting of the said bracket 11.

It will be understood that the dispenser 10 consists of a tubular container 12 elliptical in cross section as illustrated in Fig. 7 of the drawing, an ejecting piston 14 being operatively arranged within the lubricant receiving chamber 15 of the container, the resilient feeding of the piston being regulated by the tensioning means 16 as set forth in my above named patent. I

The feeding bracket 11 comprises a post 17 having a tubular arm 18 perpendicularly projecting through the head 20 of the said post 17. A U-shaped flange 21 is provided upon one side of the container tube 12 to i post 17 is adjustably secured at its lower lid by means of a suitable bolt A sleei'e is arranged through which the arm 18 is slid-ably positioned. while a helical feed spring surrounding the arm 18 being t nsioned between the post head 20 and an listing nut adjust-ablythread- Relative rotation between the sleeve .8 and arm 18 is prevented by means of key 26 slidably arranged through slots in the diametrically opposite sides of the Said arm, the said hey also extending through the opposite sides of the sleeve bei; remoyably retained in such arrangement oy c tter pins 28, it being un derstood that the arm 18 is normally prevented from being *ithdrawn from the sleeve by means of the said key 26 while sepan tion of said elements may be effected upon removing the hey.

it swivel head 29 forms a portion of the bracket 11 for connecting the sleei'e with a stationary bar fixed to the vehicle frame. A journaling member or axle 31 radially projects from the sleeve 23 upon which a collar is journaled, a short tube 33 being carried by the said collar extending perpendicularly with respect thereto and adapted for slidably mounting upon the bar 3thv the same being secured in its adjusted position thereon by means of set screws 3%. An annular nan e 35 is pro ided upon the axle 31 spaced rom the sleeve 23 forming an out. stop for the inner side of the collar 32 while an adjustable stop or cap 36 is arranged for the other end of the collar being adjustably positioned upon the reduced end 3'? of the axle 31 and being either journaled or threaded thereon as desirech the same being herein illustrated in threaded engagement therewith. A coil spring 38 encircles the axle having); one end thereof seated in a desirable one of several soclre a which he 39 arranges in the axle while the opposite end of t e spring is positioned within h aslot d0 in the te being retained therein by the said cap 36 lVhen the cap 36 is in its seated position within the end of the collar 32. the same forms a ournal member for the collar and is locked in p "'tion upon the axle portion 3? by a nut ll while the movement of the collar 32 upon the said axle is lii ted by means of a radially stop lug arranged at the L l 1' side of he tube for engu einent by a lever 43 rat lv carried by the can It will be unde ood that with the spring positicnet. with its opposite ends in one of the sockets ciently strong the cap lid locked in position by nut 11. wherei arenas by the spri 38 will resiliently maintain the lever normally in contact with the lu The tension of the spring 38 is such as so to id to lower the post 17 and tilt the forward end of the dispenser downwardly, it being understood that pressure exerted upon the forward end of the dispenser tilts the post 17 upwardly and further tensions t spring 38 and removes the lever l8 away fl cm the lug l2, the elements having the tendency to return the lever 43 forwardly in contact with the said lug.

The contact tube 13 is remoi'ably secured in any desired manner within the forward flange ll of the container 12 as by means of opposite bolts secured through ll-shaped side lu s 4:6 and l? carried respectively by the contact tube 13 and the container 12. The cross s ctional area of the tube 13 is greater than that of the container lflyit be- I tirely filling the same and presenting a broad c contact surface for engaging the wheel.

The complete operation of the device will be apparent as the contact tube face 45? is positioned upon the wheel engaging the tread thereof as best illustrated in Figs. 5 and 6 of the drawings the same being ac complished by forcing rearwardly the arm 18 and compressing the spring 25 The spring 2% thereupon feeds toe entire dispenscr l0 forwardly with the tube 13 in contact *ith the wheel compensating for wearing away of the contact tube, the length of travel of the arm 18 permitted by the lie 26 being sufficient to feed the dis penser 1O forwardly until contact tube 13 is substantially worn out. The spring 38 allows the dispenser 10 to be forcibly tilted above the wheel the same automatically returning to its operative posit-ion upon being released, the action of the spring 38 being limited by the lug 4-2 when contacted by he arm 43. The contact tube l? is provided with oppositely extending base flanges adaoted to receive any overflow of the lul *icant and preventing the same from covering the tread such as 51 of the wheel for the lubrication of the flange l8 for which the device is arranged.

In Figs. 1O, 11, and 12 of the drawings 1 have illustrated the lubricator identically with that forth in Fig. 5 of my former Patent No. 1486.001 and herein referred to with the exception that the contact tube 53 is rigidly secured to the container 54:, the entire dispenser 55 including the said con.- tainer and contact tube being shiftably mounted directly upon a mounting bar 30 b means of a swivel head 56 similar to the t ofore. described. An expell' piston is arranged within the container for projecting the lubricant from the chamber 58 therein to and through the contact tube having an enlarged opening The head 56 is provided with an axle 31 radially projecting from a sleeve 23 through which the container 54. is slidably positicned. A feed spring 24' is tensioned between a lock nut 60 provided upon the container 5% for the contact tube 53 and an adjustable nut :25 threaded upon the sleeve 23. A

collar 32 is journaled upon the axle 31 bearing a tube 33 carried therebyand secured to the bar 30 by screws 34. The remaining elements of the swivel 56 as well as the operation thereof are identical to those of the swivel head 29 and need not be again described, it being noted that the cap 36" is freely positioned upon the extension 37 oi the axle 31. The contact tube has laterally projecting side flanges This form of mount For the lubricator is especially serviceable .t'or mounting upon spring su jaported members such as the rail 38 or a car body, the dispenser being opcratively arranged with respect to the flan e l8 of a wheel as illustrated in Fig. l2 thereof. the tube 54: being fed forwardly by the spring 2% with the contact tube 53 in engagement with the wheel while the spring 38 of the swivel head 56 tends to swing the contact tube toward the wheel. A service able device is arranged which affords a large area for the lubricant being dispensed and the same may be mounted either rigidly with he wheel traveling means, or upon the spring carried frame of the vehicle. The arrangement is such that the contact tube is maintained operatively against the wheel during all varying trallic conditions. 7

It will be understood that the present dispenser is adapted for employing both soft and hard lubricants, being especially adapted for dispensing the jelly like form of lubricant wh ch readily fills the enlarged feed member when projected therein by the piston of the dispenser, its action being by reason of the retarded outflow of the lubricant by reason of its operative engagement with the wheel being operated upon. It will be noted that the feed members herein shown are slightly arcuate in form for adapting the bearing end thereof to the periphery of a wheel. the lubricant collecting base flanges of the feed members being arranged upon the same are as the adjacent side of the feed member for permitting the forward ends of the said flanges to conform to the curvature of the wheel. A lubricant spray may be employed within the feed member if desired.
